AS and A2 Biology Syllabus 9700
Recommended Prior Knowledge
Candidates should have at least a Grade C in IGCSE or 'O' level (or the equivalent) Biology or Coordinated Science (Dual Award Science).
Teaching Order
The AS and A2 courses could be taught following the sequence of Units listed below.
At AS, as an alternative, Unit 2 could precede Unit 1. It is recommended that these two Units are dealt with early and before AS Units 3 and 4. It would be possible to
cover Unit 5 earlier if desired, for example to enable study of an ecosystem at a suitable time of year.

Unit 1 in the A2 course is a logical starting point but can be taught later in the course to coincide with the best time to carry out photosynthesis practicals if desired.
It is possible to deal with Unit 4 as a stand-alone Unit towards the end of the course, or to teach particular learning outcomes together with relevant knowledge covered
in Units 1 to 3. If Unit 4 is left as the final unit, it may be preferable to teach Unit 3 immediately prior to Unit 4 as there are more topic overlaps. Further guidance is given
in the ‘Outline’ section of Unit 4.

General Resources
Within the scheme of work, books which are listed in this overview are quoted using the titles only – other books suggested have the author and publisher added, with
full details in the resource list (pp.65-69) of the 2012 Cambridge International A & AS Level Biology Syllabus, code 9700.
It is recommended that the websites listed below are viewed initially to check the areas that are covered and use when appropriate. For this reason, these websites are
not always given in the scheme of work and the ‘Learning resources’ column usually contains suggestions of additional websites to view.
Especially useful websites include:
PowerPoint presentations donated by teachers
The Society of Biology (IOB and Biosciences Federation)
The National Centre for Biotechnology Education
Science and Plants for Schools
Biology 4all (many links to other useful sites)
S-cool revision
The Association for Science Education teacher resources
Biochem4schools
On-line biology book
The Molecular Biology Notebook
Kimball’s Biology Pages (especially useful for teacher reference)

General websites such as http://en.wikipedia.org/wiki/Biology are useful for extension or extra reading. Check articles first for accuracy, for example against information
on websites that end in .edu (USA) or .ac.uk, or against tertiary level, or research, institutions elsewhere, before recommending a particular topic. Teachers should
remind students that websites are not specifically designed for the syllabus and that they do not always provide additional information, or may be contradictory.
http://www.textbookrevolution.org/index.php/Main_Page lists free textbooks that are available online: this may be worth checking at intervals and, for students to revisit
GCSE topics, http://www.biology-resources.com/ is an excellent site.
Other resources:
The most useful single text book is AS and A Level Biology, Jones, Fosbery, Taylor and Gregory, published by CUP (ISBN 9780521703062) and endorsed by CIE.
For practical work, Practical Advanced Biology, King, Reiss and Roberts, published by Nelson Thornes (ISBN 9780174483083) and Comprehensive Practical
Biology for A Level, Siddiqui, published by Ferozsons (ISBN 9690015729) are both excellent. Bio Factsheets, published by Curriculum Press, cover a wide range of
topics and are useful for revision and extension work http://www.curriculum-press.co.uk/ . For Unit 4 of the A2 course, Applications of Biology* provides helpful
information and gives a guide to the level of detail required. Teaching AS/A2 Biology Practical Skills* are two CIE publications useful for planning practical sessions
that will help students develop the necessary skills. *CIE Teacher Support website and from CIE Publications.
A revision guide has been published for this syllabus: Cambridge International A/AS-Level Biology Revision Guide, Jones, published by Hodder Education (ISBN:
9781444112672). The current Biozone International Ltd publications do not match this syllabus, but centres that have Biozone (2004) Advanced Biology AS and A2
– Student Resource and Activity Manuals, (ISBN 9781877329968, 1877329223 – Model Answers ISBN 9781877329975), will find that many learning outcomes in this
syllabus are covered.

As symbols, signs and abbreviations used in examination papers follow the recommendations made in Biological Nomenclature (4th Edition), published by the
Society of Biology (formerly the Institute of Biology), this publication should be consulted. http://www.societyofbiology.org/education/educational-resources/bnn
The CD- ROM, BIOSCOPE is a very realistic biological microscope simulation (Cambridge-Hitachi) ISBN 9781845650261) accompanied by paper-based tasks (in
Word and PDF format). There are 56 high quality slide sets of plant and animal specimens and students are also able to learn how to use an eyepiece graticule and a
stage micrometer scale. http://www.cambridge.org/gb/education/secondary/subject/project/item404911/?site_locale=en_GB
Reinforcement and formative assessment
It is recommended that, towards the end of the time allocated to each of the units, time be taken to permit reinforcement of the learning that has occurred. There are
many ways in which this might be done, ranging from revision lessons, through overview homework, through research project and into preparation of essays
(particularly useful for the extended questions in the A2 examination), presentations, posters or other material. AS and A level Biology, has useful self-assessment,
and past examination, questions, both with answers. Groups of two or three students should be encouraged to work together for an hour or two of lesson time, plus
homework for a week or two. They should prepare a presentation of a topic to their peers. This could be in the form of a poster, a video/video clip, a PowerPoint
presentation, an OHP illustrated talk or whatever seems appropriate. Biology topics, with so much attractive visual material, are very well suited to highly visual
presentations. Some students will wish to draw their own diagrams, and others to download them from the net, and others to photocopy them from paper sources – all
these approaches should be encouraged.
Formative assessment could take the form of mini-tests, taking just 10 or 15 minutes for students to do and then mark for themselves, perhaps using questions from
online question banks such as http://www.learncie.org.uk/ – discussing the correct answers as a whole class. At the end of the unit, there should be a much larger
formative assessment test, using appropriate past-examination and similar style questions, taking a lesson to do, and a lesson to provide feedback after marking by the
teacher. Past papers from which to select questions can be obtained from the CIE Teacher Support website. Note that providing students with the published mark
scheme for a question has limitations and is not recommended unless further guidance is given by the teacher. The mark scheme for each question paper must be
used by the teacher in conjunction with the relevant question paper and the Examiner Report. Teachers should be familiar with the abbreviations and conventions used
in the mark scheme.
